ADJUSTABLE CULTIVATOR.SHOVEL.

SPECIFICATION forming part of Letters Patent No. 396,277, dated January15, 1889.

Serial No. 286,970- (No model.)

To all whom it may concern:

Be it known that I, HENRY C. HART, a resident of IVannakee, in thecounty of Dane and State of Visconsin, have invented certain new anduseful Improvements in Adjustable Cultivator-Shovels; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a tilting device for cultivator-shevels.

The object is to produce a cultivatorshovel which shall be of suchconstruction that it may be tilted to any desired angle relative to theplow-beam; furthermore, to produce a tilting device which shall besimple of construct-ion, efficient and durable in use, and comparativelyinexpensive of production.

\Vith these objects in view the invention consists in the improvedconstruction and combination of parts of a cultivator-shovel tiltingdevice, as will be hereinafter fully described in the specification,illustrated in the drawings, and pointed out in the claims.

In the accompanying drawings, forming part of this specification, and inwhich like letters of reference indicate corresponding parts, Figure 1is a perspective view of the tilting device detached from the shovel.Fig. 2 is a perspective view showing the same attached to the shovel,and Fig. 3 is a detail view of the base of the tilting device.

Referring to the drawings, A designates the shovel, which is of theordinary construction and made of the material ordinarily used for suchpurposes.

B designates the tilting device, constructed of a bottom or base, 1, theunder portion of which is beveled 011 each side, so as to conform to theshape of the shovel. 011 each side of this base is formed an ear, 2,provided with an opening, 3, through which the bolts 4 of the shovelpass, and by means of which it is secured firmly in place upon the same.

0 designates the cultivator-standard, constructed, preferably, of iron,and has secured at its lower end, or has formed integral therewith, twostuds, 5, designed to fit in two grooves, 6, formed on the under side ofthe base, these studs, in. conjunction with the grooves in the base,forming the pivotal point of the cultivator-standard. At a point nearthe said studs and sliding on the said beam is a yoke, 7, to the lowerend of which is pivoted, by means of a bolt, 8, a clip, 9, the lowerend, 10, of which engages two grooves, 11, in the base similar to thoseat the other end of the same, that are engaged by the studs on thecultivator-standard.

Having now described the various parts of this device, I will proceed toshow its method of operation.

The base, with the studs of the cultivatorstandard engaging the grooves011 the under side of the same and the clip engaging the grooves at theopposite end, is placed upon the shovel and is securely clamped in placethereon by means of the bolts and nuts be fore referred to. Now, shouldthe cultivatorstandard be set at an angle of, say, fifteen degrees, andit should be necessary to set it at an angle of twenty degrees, it willonly be necessary to loosen the nuts on the bolts 4, move thecultivator-standard up, and then screw the nuts on the bolts 4 homeagain,

when the beam will be held firmly and rigidly combination of the shovel,a grooved base adjustably secured thereto, a standard, and studs securedto the said standard for engaging the grooves in the base, substantiallyas described.
